The biggest problem with that layer cake is that it shows XML as part of 
the foundation, which it isn't.  XML is pretty much irrelevant.  It was 
historically used for the first standard serialization of RDF (known as 
RDF/XML).  But we now have better standard RDF serializations such as 
Turtle and JSON-LD (the latest, based on JSON).  It is very misleading 
to have XML in the layer cake.
